DEMOUNTABLE Rll AUTOMOBILES..

Application filed February 10, 1923.

'lhis invention relates to demountable rims for automobiles and has 'for its object i provide a rim ot this character capable ,sing readily disassembled to facilitate .e application or removal ci a tire.

lt is also an object et the inventlon to provide means ot this character wherein the tire casing` may rest upon an unbroken sur- 'tacc and yet is firmly clamped by the sections ot the demount-able rim.

lt a tt'urther object ot the invention to nrovide a device ot' this character capable oli lfeinnj held in engagement with the wheel and `thc tire by lugs carried by the telly of he wheel.

lt is a 'further object ot the invention to provide a device ot this character including' a wheel rim section and a tire rim section which coact to provide a compartment having' a. clamping rim section to permit the heads ot the tire to enga-,qe a smooth surtace, thus eliminating wear and possible damage.

it is a still further object of the invention to provide a device of this character wherein the wheel rim section is provided with tastening means normally disposed with.- in the compartment for engagement with means carried by the clampingrim section to permit the rim to -be used for holding` a spare tire without requiring use of the rim 'fastening lugs.

lilith these and other objects in view, the invention consists in the improved construction and arrangementot parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a. transverse .sectional view ot a demountable rim constructed in accordance with an embodiment ot the invention;

Figure 2 is a transverse sectional View ot another torni of the invention2' Figure 3 is a detailed sectional vieu* ot Jche clainjnng element shown in Figure 2; and

Figure 4l is a plan view of the hook shown in Figure 2.

Referring' to the drawings, 5 designatesa wheel uponv which a wheel rim section 6 is disposed. The section 6 has al supporting` flange T on one edge thereof, while the opposite edge portion is reduced to provide a recess or depression 8, the recess or depressien 8 being disposed adjacent the edge ot the wheel This rim section is secured to Serial No. 618,214.

the outer surface ot the telly ot the wheel and serves as mea-ns for supporting and assisting in the clamping' operation .of the removable riin sections to be her. matter described.

In connection with the section 6., a tire rim section 9 is provided. This section includes a holding flange 10 which is extended in angular relation to the body portion ofthe section and is intended to engage one side of the tire A.. rThe wid-th of the rim section 9 is greater than the width of thesection @so that the side portion 1j1 of .the section 9 projects beyond the adjacent edge portion of the section `6. By this means the side Vportion 11 coacts with the depression 8 of the section 6 yto provide a compartment 12 which extends annu-.lafrly ot' the .rheel.

vIn connection with the Vtire rim `section 9, a lclan'iping rim section'll is provided. This section consists of a body portion `14- havlng a flange 15 which corresponds Vto the flange 10 of the tire vrim section, the 4flange 15 being` wider than the flange 10 Aso as to project beyond. the side portion 11 of the tire rim section and to substantially coacrI with the flange 10 to hold a. tire. The inner edge 16 of the `body portion 14 is intended to engage the inner walll ot the depression or recess 8 to limit movement of the clampinn; lsect-ion inwardly of the compartment. The edge of the -side portion 11 of .the tire rim 'section is lalso intended to engage the inner Jface oi the flange' 15. i i

Proj ecting through the telly 5 ot the wheel is a plurality ot bolts 17 having their threaded ends projecting beyond the side of the .telly adjacent the flange 15 for the reception of clamping lungs 18. each of said lugs having); its end portion 19 offset for engagement with the outer surface ot the flange 15 of the clamping section 13. These lugs are held in engagement with the wheel by nuts 2O threaded on the project-inn"v ends of the bolts.

l/V hen it is desired to remove the tire the lugs 18 are released and the clamping section moved outwardly from the compartment 12, thereby releasingthe wheel rim section. The tire may then be removed as well as the tire rim section without difficulty.

In Figures 2 to 4. another form of the invention is shown. This form comprises a wheel telly 21 having a portion of its surface reduced to provide a depression 22. A

section 23 is provided for the felly. This section has one side Vportion formed into a holding` flange 24 While the opposite side portion 25 is offset and disposed Within the depression 22. A tire'rim section 26 is provided, said section corresponding in structure to the tire rim section 9 and includes a tire engaging flange vThe side portion 28 of the tire rim section is intended to eX- tend over the offset portion 25 or the wheel rim section so as to coact with said offset portion to provide a compartment. Depending from the inner face of' the .side portion 28 of the tire rim section are lugs 29, said lugs being disposed at spaced intervals annularly of the section. These lugs are intended to receive hooks 291said hooks being movable Within the compartment.

In connection With the tire rim section, a. clamping rim section 30 is provided` The body portion .31 of saidsection is intendedv to be disposed Within the compartment Jfornied by the offset portion 25 of the rim`23 and rim section 26. The clamping rim section also includes a flange 32 which is intended to substantially coact With the flange 27 to clamp a tire to the Wheel. Depending from the inner face of the body portion 31 is a plurality of studs 38, which are spaced annularly of the clamping rim section. These studs, When the vbody portion 3l is disposed Within the compartment, are intended to be engaged bythe hooks 29a so as to urge the inner edge of the body member 3l in engagement vWith the inner Wall ofthe offset portion of the Wheel rim and thus permit a spare tire to be held Without the use of clamping lugs, each hook being provided with finger piecesV 34.

The clamping lugs may also be used to permit this form of the invention to be used for holding the tire on the wheel as the studs and ratchet hooks are normally disposed Within the compartn'ient.

From the foregoing it will be readily seen that this invention pro fides a novel form of demountable rim capable of being operated by anyone Without unnecessary strain. In addition to this the rim is composed et' only a small number of simple parts capable of being applied to the conventional type of Wheel. y

that is claimed is A demountable rim comprising a main rim section including a circular band having at one edge thereof a flange and having upon its inner surface adjacent the opposite edge thereof and at circumferentially spaced points inwardly extending lugs and a continuous complementary rim section of less internal diameter then the main rim section, .said complementary rim section comprising a band telescopically engageable with the band of the lirst named rim section and having at one side thereof a flange limitingT such telescopic engagement, the inner face ot the band of the complementary section being provided with a plurality ofl inwardly directed lugs corresponding in number and arrangementv to the lugsv of the band of the main section, the lugs of one ot .said bands having mounted thereon hooks engageable With the lugs ot' the other ofthe bands to maintain the sections in, assembled relation, the inner ends of coacting lugs of the main and complementaryV rim sections being arranged in common planes and being adapted to seat at their inner ends upon the reduced portion of a wheel felly with Which the main `rim section .is engaged.

In testimony whereof We hereunto ailix our signatures.
